Sole structure of golf shoes

ABSTRACT

A sole structure of golf shoes comprises a plurality of plastic spikes, a plurality of anti-slip pads, a textile and a light weight sole made by EVA (ethylene vinyl acetate). The plastic spikes and anti-slip pads are formed via injection molding to pierce through and mount on the textile. The textile be cut into a shape of the sole and bonded to the sole. Thus the spikes do not drop or get lost easily. Repair trouble can he reduced and use cost is lower.

FIELD OF THE INVENTION

The present invention relates to a sole structure and particularly to a plastic spike holding structure be used On the sole of golf shoes.

BACKGROUND OF THE INVENTION

Golf is a sport that requires precision and accuracy. It does not require athleticism like other sports do. It's mainly for the golfers to walk on various sorts of terrains and swing their golf clubs. At present, it is one of the most popular sports in the world that is suitable for teenagers, the middle-aged and elderly people. However, when walking on the grass, especially the wet and slippery ones, if the grip of the shoes is not strong enough, the golfers could easily get slipped and fall. And it could cause serious injury to people of old age or suffered from osteoporosis.

Therefore, to prevent people from slipping and falling while walking on the grass field and result in sport injury. Shoes specially made for golf tend to have soles (as sketch sole 2) with plural spikes (as sketch spike 1) in order to increase the grip on the grass field and reduce the risk of slipping and falling.

The conventional sole of the golf shoes has a receptacle (as sketch receptacle 3) embedded in the sole. The receptacle could be made of metal or plastics, and the sole has to be made more thick than regular sole to get more space for the receptacle, and it will increase the weight of the shoes to be heavy.

At present, most of traditional golf shoes must insert receptacles into rubber sole which is the most heavy sole material in the market today, and it could be burdens to the golfers during long time walking while play golf. Also, some traditional golf shoes use TPU (thermoplastic polyurethane) sole with receptacle, but TPU is too hard and not comfortable for wear.

Moreover, the traditional spike, whether made of plastics or metal, it needs to be fastened into the receptacle on sole by spike wrench (the latch or screw extended outwards), after walking for a long time, it could get loose or drop down, because of vibration or impact caused by walking. Namely, the spike could easily get loose or drop down while playing golf, it's inconvenience for the users that must to buy new spikes for repair, it takes time and extra expenses, and it might not be able to find spike with the same type or same color in the market. Therefore, the sole might not look as good as it supposed to be.

By the way, after the spikes get loose and drop down, the grip of the shoes will be decreased, if the user is not aware of the loosing of the grip of sole, the risk of slipping or falling will be increased. Hence, after the golf game, users have to examine the spikes, fasten them up and see whether replacements are needed. Moreover, the proper fastening of every spike also has to be examined before the game started.

To inspect whether the spike is tightly fastened or not, a spike wrench is needed. However, it's inconvenience, also extra cost of repair and maintenance. All these indicate, due to the restriction that the receptacle of traditional golf soles can only be placed in the sole, it had been difficult to break through the obstacles in reducing the weight of the sole/shoe and cutting down the cost,

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a sole structure with spikes that do not drop to eliminate repair trouble and reduce the cost.

Another object of the invention is to provide a lighter weight of sole/shoe to help relaxing while play golf.

To achieve the foregoing objects, the invention provides a sole structure of golf shoes which remove receptacle to make more thin sole, also don't use heavy rubber sole and hard TPU (thermoplastic polyurethane) sole. The sole structure of the invention comprises a light-weight sole made by EVA (ethylene vinyl acetate), a textile, plural plastic spikes and anti-slip pads. The textile has a. bonding surface and a mounting surface. The plural plastic spikes and anti-slip pads are made via injection molding to pierce through the mounting surface of the textile, then, the finished textile with plastic spikes and anti-slip pads be cut the shape of the sole, and the textile bonding surface cement to the bottom of the light-weight EVA sole, then, the new structure of golf sole be completed.

Under technical assistance, the spikes with anti-slip pads piercing through to textile back by injection molded, and cement to the light-weight EVA sole, the mounting surface and bonding surface of the textile can form secure connection with the plastic spikes and anti-slip pads and light weight EVA sole. Thus the bonding of textile with plastic spikes and anti-slip pads and light weight EVA sole are very good and past lab test. Moreover, the plastic spikes and anti-slip pads can be firmly fastened to the bottom side of the light weight EVA sole. The sole thus formed has at least the following features:

1. Through the textile treated via the injection molding process, an inter-fusion state is formed between the textile and plastic spikes and anti-slip pads without a distinguishable interface, and a stronger bonding force is also formed, so, the plastic spikes are less likely to loosen off or drop under vibration or impact during walking in the sport.

2. With the plastic spikes directly bonded to the light weight EVA sole through fusion without loosening off, the trouble and cost of replacing the spikes that might otherwise occur can be resolved. The problem of buying the new ones for replacement for the lost plastic spikes also can be eliminated,

3. As the lifespan of the plastic spikes is substantially the same as the light weight EVA sole, when the plastic spikes are worn and become unusable, the light weight EVA sole also is broken about the same without repair value. Thus they can be just discarded and replaced by the new ones to reduce the trouble and annoyance of repair.

4. To use plastic spikes, no need receptacle to get thin sole, no need heavy rubber sole, thus, we got a super light weight sole and shoe, at present, one conventional sole of the golf shoe weight about 200 to 350 grams, the sole of the invention, according to design differences, weights merely 80 to 120 grams, thus can be made even lighter to reduce user's wearing burden.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED Embodiment

Please refer to FIGS. 2 and 3, the present invention comprises a light weight sole 10 made by EVA (ethylene vinyl acetate), a textile 20 and a plurality of plastic spikes 30. The textile 20 can be a fiber cloth, a woven cloth, a non-woven cloth or the like. The textile 20 has a bonding surface 21 and a mounting surface 22. The plastic spikes 30 are formed via injection molding to pierce through and mount on the mounting surface 22 so that they are bonded to the textile 20 to form a sheet. The textile 20 is cut in a shape of a sole 10. The bonding surface 21 is bonded to the bottom side of the light weight EVA sole 10.

The invention further includes a plurality of anti-slip pads 40 formed via injection molding to pierce through and mount on the mounting surface 22 to reinforce the textile 20.

In short, in the invention, with the plastic spikes and anti-slip pads piercing through and mounting on the textile via injection molding, an inter-fusion state is formed between the textile and plastic spikes and anti-slip pads without a distinguishable interface. In other words, the plastic spikes of the invention can be securely fastened to the bottom side of the light weight EVA sole without loosening off and dropping under vibration or impact during walking, hence the trouble and annoyance of repair can be reduced. Moreover, the invention is simply structured, hence can save material and further reduce the weight to meet use requirements.
